一种数字式全隔离信号采集电路的设计

摘要

This passage design a signal acquisition circuit of digital high speed and full isolation. By using the V/F, F/V transformation to realize the transmission of analog signals, and using the infrared communication to realize the acquisition and processing board between class communications, using the high-speed A/D to realize implementation of the analog signal acquisition.%设计了一款数字式高速全隔离的信号采集电路。以V/F、F/V变换实现了模拟信号的传输，以红外通信来实现采集板和处理板之间的通信，以高速A/D实现了对模拟信号的采集。经测试，达到了预期的设计效果，具有较高的实用价值。
